Evaporator outlet
Conductive
paste
Important Note
• Mount the sensor on a clean
paint-free surface.
• Remember to use heat
conducting paste and insulate
the sensor.
• For precise measurements,
mount the sensor max. 5 cm
from the outlet of the evaporator.
Evaporator
Sensor mounting: Temperature sensor
Pressure transmitter
• Installation of the pressure transmitter is less critical. However, the pressure transmitter should be closer to
the temperature sensor, right after the evaporator and with its head upright. It is a good practice to select
a pressure transmitter with an average load of 40 - 60% of full scale.
• 5 EKEs at maximum are allowed to share the output signal of a ratiometric pressure transmitter.
In order to get a correct acquisition on all the units all the three wires (GND, 5 V and transmitter signal
output) must be routed to every unit.
Power supply
• Power sharing is allowed in EKE controller.
• It is a good practice not to reverse the polarity of the power connection cables.
Selection of the common power supply depends on the total number of sharings and the valve in use.
